Pentek Brand Compatible Carbon Pre and Post RO Filter to replace GE FX12P (2pack) The Pre filter is the EP-10 which is 5 Micron and the Post is CCBC-10 which is 1 Micron filter. Coconut based carbon block cartridges are highly effective at reducing unwanted taste & odor and chlorine taste & odor from potable drinking water, and they are equally effective at reducing fine sediment.*Coconut based carbon block cartridges are manufactured using a patented process and are made from a water-washed, coconut-carbon formulation. This process and media yield a cartridge with high chlorine taste & odor reduction capacity.These cartridges are protected by Endurawrap, a uniquely formulated polyolefin bilaminate pre-filter, designed to significantly increase the useful life of the cartridge by trapping sediment that typically plugs carbon block cartridges.They are an ideal choice for a wide range of residential, food service, commercial and industrial applications. They also make excellent polishing filters or pre-filters in applications requiring fine filtration and high capacity.EP Series carbon briquette cartridges are manufactured using a patented process that yields a cartridge with a nominal 5-micron filtration rating, high dirt-holding capacity. A high porosity design helps prevent the cartridge from plugging before its adsorption capacity is exhausted, maximizing the utilization of the carbon while maintaining low pressure drop.These cartridges are protected by Endurawrap, a uniquely formulated polyolefin bilaminate pre-filter, designed to significantly increase the useful life of the cartridge by trapping sediment that typically plugs carbon block cartridges.EP Series cartridges are manufactured entirely from FDA-compliant materials making them an ideal choice for a wide range of residential, food service, commercial and industrial applications.Pentek is the largest brand in the filtration industryPentek is the originator of carbon block production technologyPentek is the largest producer of carbon blocks worldwide
